Comparison between Threshold Pupil Perimetry and Suprathreshold Pupil Perimetry
Purpose: Pupil perimetry has so far been performed by the two following methods: suprathreshold perimetry during which the amplitude or ratio of pupil constriction is determined, and threshold perimetry during which the threshold of pupil reaction is determined. The authors compared the values obtained with these two methods using the modified Octopus 1-2-3. Subjects and methods: Pupil perimetr...
متن کاملNew approach for the glaucoma detection with pupil perimetry
OBJECTIVE To calculate the pattern deviation for identifying abnormal points of pupil perimetry, and also to evaluate the grayscale display for distinguishing glaucomatous pupil field loss (abnormal test points) from normal pupil field (normal test points). METHODS Fourteen patients ranging in age from 51 to 80 years, who had normal-tension glaucoma (6 eyes) and primary open-angle glaucoma (8...
متن کاملResearch device to preproduction prototype: a chronology.
This paper describes the evolution of the Wheelchair Aerobic Fitness Trainer (WAFT), a wheelchair ergometer developed for determination of aerobic capacity and the diagnosis of coronary artery disease in lower limb disabled persons whose mobility depends primarily on the manual wheelchair. The device was originally developed for use in research studies to determine peak exercise capacity in per...
متن کاملSpecifications and Prototype of Rheological Device
In the task 4.3 we investigated on the possibility of realizing haptic display to mimic haptic sensations by using ‘new’ technologies such as smart materials. In the previous D4.6 we preliminarily investigated on rheological properties of some controllable fluids and we explored the possibility of implementing haptic interfaces by using Magneto-Rheological Fluids (MRFs). Unlike kinaesthetic dis...
متن کاملDisplay Registration for Device Interaction - a Proof of Principle Prototype
A method is proposed to facilitate visually-driven interactions between two devices, which we call the client, such as a mobile phone or personal digital assistant (PDA), which must be equipped with a camera, and the server, such as a personal computer (PC) or intelligent display. The technique that we describe here requires a camera on the client to view the display on the server, such that ei...
